BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a blower for an air conditioner,particularly to one capable of having cold air that is circulated by anevaporator to be blown directly and powerfully from a cold-air blowerout of wind outlets of faceplates so as to achieve a prompt blowingfunction and an optimum cold-room effect.

[0003] 2. Description of the Prior Art

[0004] Generally speaking, a known conventional blower for an airconditioning system installed to an upper floor construction includesmany wind-out faceplates disposed around an indoor machine and providedwith wind outlets connected with the indoor machine by windpipes forblowing cold air into the room. Such wind outlets are provided withguide plates each made integral in a fixed form so that the cold airblown out adjacent the wind outlets is stronger than that with adistance away from the wind outlets, thus unable to provide the roomwith even cold temperature. Therefore, in order to spread cold airevenly in the room, a lot of wind-out faceplates are needed forinstallation in different locations of the room, which also requiresmany windpipes of different length to be connected with the wind-outfaceplates. However, cold air transported through such windpipes ofdifferent length is hard to keep the same cold temperature when it isfinally blown out of the wind outlets of the wind-out faceplatesinstalled in different locations, thus still unable to achieve an evencooling effect in the room.
